While it is *technically* possible to use them and not have problems there is a high probability that you will. Should you be unfortunate enough to encounter one you might as well consider your money GONE. They seemingly lock cards at random and will not under any circumstance return your money to you without providing them with a birth certificate or passport or other really sensitive information. Many people have been ripped off by these guys even AFTER forking over all their identification. If you are looking for a prepaid service to use stay FAR away from this one. They are not to be trusted.
